In 1965, Australian medical device pioneer Noel Gray established Telectronics – Australia’s first manufacturing facility for producing pacemakers that were designed in-house. Telectronics was an innovative developer, achieving some major successes in the early cardiac pacing field, for example, Telectronics’ leads allowed narrowing the pacing pulse to its current nominal of 0.5 milliseconds; encapsulating the pacemaker in titanium instead of epoxy; using a microplasma weld to join the two halves of the pacemaker capsule; creating one of the first rate-responsive ‘demand’ pacemakers; and isolating the pacemaker’s battery in a separate compartment to deal with the problem of leaking mercury-zinc batteries.

Image Credit: St. Jude Medical
The DF-4 Connector was recently introduced by a joint group of CRM companies, physicians, and regulatory agencies as a way of easing the implant of ICDs by reducing defibrillation connections from three to one and by minimizing the number of set screws. Prior to the development of the DF-4, traditional high-voltage connector systems required up to three connections. Continue reading

Remon Medical’s Implantable Pulmonary Pressure Sensor (1997-2007)
Remon Medical Technologies, Ltd. was founded in 1997 in Caesarea, Israel to develop implantable, wireless pressure sensors.
Remon developed an implantable hemodynamic monitor, which allowed on-demand, non-invasive, leadless self-monitoring of pulmonary artery pressure by the patient at home. ImPressure devices were placed in the pulmonary artery, and transmitted pressure readings to a hand-held monitor. It was hoped that the system would provide early warning of the need for treatment, avoiding hospitalization and deterioration in the patient’s condition. Continue reading
SMSI® Implantable Glucose Sensor
Sensors for Medicine and Science, Inc. (SMSI) of Germantown, MD was founded in 1997 to develop chemical sensing technologies based on fluorescence sensing.
SMSI® is now developing an implantable glucose sensor that is designed to automatically measure interstitial glucose every few minutes. The sensor implant communicates wirelessly with a small external reader, allowing it to track the rate of change of glucose levels and warn the user of impending hypo- or hyperglycemia. According to SMSI, the target operational life of the sensor implant will be 6-12 months, after which it would be replaced. Continue reading
St. Jude Medical’s Active Implantable Sales for 2011: CRM Down 3%, Neuromodulation Up 8%
St. Jude Medical today reported sales and net earnings for the fourth quarter and year ended December 31, 2011. From the press release:
“Cardiac Rhythm Management
Total CRM sales, which include implantable cardioverter defibrillator (ICD) and pacemaker products, were$728 million for the fourth quarter of 2011, a 4 percent decrease compared to the fourth quarter of 2010. After adjusting for the impact of foreign currency, total CRM sales decreased 6 percent. Total CRM product sales for the full-year 2011 were $3.034 billion, essentially equal to 2010. On a currency neutral basis, total CRM sales declined 3 percent from the prior year. Continue reading
Elema-Schoenander and the Very First Human Implants of a Pacemaker in Sweden (1958) and Uruguay (1960)
This is a picture of the first pacemaker to be implanted in a human patient. It was developed by Dr. Rune Elmqvist (1906–1996), a physician by training, but working for the Swedish company Elema-Schonander as an engineer. Dr. Elmqvist developed the device in cooperation of Åke Senning, senior physician and cardiac surgeon at the Karolinska University Hospital in Solna, Sweden. Continue reading
“Data Block” Percutaneous Implantable Electrical Connector
Data Block implantable percutaneous electrical connector produced by Intermedics for in-house animal studies. Device accommodated two IS-1 bipolar leads and had an IROX-coated "can" electrode.
The development of medical devices, drugs, and treatments depends on accurately retrieving clinical data from implanted animals. Implantable data collecting and sensing devices provide one way to retrieve these data. These device often include sensors or electrodes which must be implanted within the subject in order to provide clinicians with access to the sensed information.
Retrieving data from implanted sensors poses a potential problem since data frequently must be retrieved on numerous different occasions and over an extended period of time. If surgery is required each time data is retrieved, the subject may be overly exposed to stress, trauma, or risk of infection. In order to develop and test cardiac pacemakers and defibrillators, for example, clinicians need to monitor electrical activity of the subject’s heart. One way to monitor this activity is to surgically implant one end of a lead to the heart. The other end of the lead may be left subcutaneously (i.e., under the skin) or transcutaneously (i.e., through the skin). In the former instance, access to the electrode may require an invasive procedure, such as surgery. In the latter instance, prolonged and chronic exposure of the electrode through the skin may cause discomfort, lead to infection, or cause damaging stress on the electrode. Continue reading

Neuromed’s TIME Battery- and RF-Powered Totally Implantable Multichannel Spinal Cord Stimulator (ca. 1988)
Neuromed TIME IPG on loan from Daniel Villamil's collection.
Neuromed was formed in 1980 with an initial capitalization of $150,000 by Bill Borkan through money obtained when Borkan`s parents took out a second mortgage on their home. Borkan’s desire to help his sister, Jennie, a cerebral palsy patient, got him started in neurostimulation technology. In the next few years, Neuromed developed and marketed a RF-powered implantable spinal cord stimulator, along with its external radio frequency transmitter.
Throughout the 1980s, development of more advanced devices was ongoing at Neuromed. My friend Daniel Villamil from CCC Medical has in his collection one of these more modern units, which he lent to me for photographing. The “Total Implantable Multichannel Electronics” (TIME) spinal cord stimulator shown in this picture went into clinical trials around 1988. This was a device that was internally powered by its own battery. However, it could also be RF-powered after the eventual battery failure. Continue reading
St. Jude’s (ANS) Rechargeable Spinal Cord Stimulators Eon and Eon Mini
In 2005, St. Jude Medical purchased Advanced Neuromodulation Systems (ANS) in Plano, Texas. ANS had developed a number of spinal cord stimulation IPGs that were either externally powered via inductive link, internally powered by a primary cell, or internally powered by a transcutaneously rechargeable lithium-ion cell.
Today, the most popular St. Jude spinal cord stimulators are the rechargeable 42 cc Eon and 18 cc Eon mini neurostimulators.
They are constant-current devices with a rated longevity of 10 years. Current through up to 16 electrodes is programmable between 0-25.5 mA with a pulse width of 50-500 µs and a frequency between 2-1200 Hz. Continue reading
Intermedics’ First Pacemakers (Mid 1970s)
In 1973, former Medtronic sales representative Albert Beutel founded Intermedics in Freeport, TX. The first product was a small, mercury-cell-powered pacemaker. In 1974 Intermedics introduced a lithium-powered version, and in 1976 it introduced InterLith which was hermetically sealed, and weighed just 65 grams. At the time, InterLith’s size was a breakthrough, and became a very popular device, solidifying Intermedics’ position in the industry.
